Description
Technical field
The present invention relates to a kind of grease distributor, especially relate to a kind of multiple exit grease distributor.
Background technique
At present, in the industries such as metallurgy, mine, building materials, generating and large-scale engineering machinery, original oil box oil supply mode is eliminated gradually in these applications, and applies more lubricant oil, the dispensing device of lubricating grease and system and mainly contain following two kinds: 1, single-line type divides oil system and single-line type separating valve; 2, two-wire system divides oil system and two-wire system separating valve.
Single-line type divides the shortcoming of oil system and single line separating valve comparatively obvious, as long as be exactly certain lubricating point blocking of certain distributor, the institute of this distributor a little all quits work.Comparatively complicated in system, when lubricating point is more, single-line type divides oil system and single-line type separating valve to be easy to the situation occurring because of the blocking of indivedual lubricating point working.Meanwhile, the volume read-out of same distributor can only be identical, can not regulate arbitrarily, and be easy to blocking.
Two-wire system divides oil system and two-wire system separating valve to have following advantage: the function that 1, can realize quantitative fuel feeding.2, have two oil supply loops in system, compared with dividing oil system and point oily device with single-line type, system is not easily collapsed, but the separating valve in this system easily causes oil pump separating valve nearby to bear high pressure and the separating valve underpressure far away apart from oil pump.This system dynamic sealing point is more in addition, and system easily occurs oil leakage phenomenon.
The use solenoid valve occurred in recent years is as the lubrication system of oil supply device, and its principle is connected to solenoid valve between fuel supply line and lubricating point, uses PLC to carry out the switch of Controlling solenoid valve.Also oiling (fat) amount that just have adjusted lubricating point on time of adjustment solenoid valve.The lubrication system of solenoid valve is used to have following shortcoming: 1. normal open fault easily occurs solenoid valve, particularly more at lubricating point, in the lubrication system using solenoid valve also more, as long as there is a solenoid valve generation normal open fault, the waste of lubricant oil and the reduction of system oil pressure will be caused, the grease out of multithread simultaneously will leak out, and pollute working environment.2. solenoid valve commutation thrust is less, because dry oil viscosity is comparatively large, has delayed the turn around time of solenoid valve, has caused measuring error.When ambient temperature is higher, electromagnetic push obviously declines simultaneously.
Chinese patent 200420029881.1 discloses a kind of multi-point self-lubricator, comprising a kind of rotating circulating distributing valve distributed for lubricating grease, this valve is by the valve body fixed and be in transmission connection in drive motor by driving component and the rotatable spool being packaged in valve body by end cap is formed, and spool is provided with cavity.The advantage of this valve is that oil circuit is without undue narrow, to the impurity strong adaptability be mixed in lubricating grease, long service life, not easily blocking, but simultaneously this valve also has its shortcoming: this valve itself can not control lubricant oil to oil mass, each lubricating point be identical to oil mass.There is no the advantage such as existing above-mentioned impurity strong adaptability, long service life, not easily blocking in the market, accurately can control again point oily device of arbitrfary point any lubricant oil oil mass.
Summary of the invention
Technical problem to be solved by this invention is to provide the impact that a kind of applicability on oil product is strong, measuring accuracy is not subject to the change of ambient temperature and system pressure, and the multiple exit grease distributor that the pressure loss is little.
In order to solve the problems of the technologies described above, multiple exit grease distributor provided by the invention, comprise a distributor body and distributor mandrel, the drive unit be in transmission connection with described distributor mandrel, be located at multiple valve body oil outlets of different stable state position on described distributor body, described distributor mandrel be provided with mesopore and multiple in different stable state position respectively with multiple described valve body oil outlet spool oil outlet passage of being communicated with corresponding to described mesopore, described distributor body is provided with the filler opening that can be connected with high pressure oil, a gear motor is provided with in described distributor body, the entrance point of described gear motor is communicated with described filler opening, the outlet end of described gear motor is connected with the described mesopore of described distributor mandrel, the oily flow sensor of described gear motor as drier oil and the actuator of volumetric metering device, then by photoelectricity and snubber output signal, realize accurate measurement and oil and spread sense.
Described drive unit is stepper motor.
Described metering mechanism is Gauss meter measuring device.
Adopt the multiple exit grease distributor of technique scheme, when high pressure oil enters distributor body through filler opening, according to the principle of gear motor, when the oil outlet of gear motor is opened, gear motor rotates.High pressure oil enters the mesopore of distributor mandrel through gear motor, when the mesopore of distributor mandrel and spool oil outlet passage be not to time upper, distributor place is as packing state, when the mesopore of distributor mandrel and spool oil outlet passage are to time upper, drier oil exports, and gear motor rotates and passes through gauge signals metering (discharge capacity that gear motor often rotates a circle) on the output shaft of gear motor simultaneously.Detect whether oil circuit blocks simultaneously.The oily flow sensor of gear motor as drier oil and the actuator of volumetric metering device, then by photoelectricity and snubber output signal, realize accurate measurement and oil and spread sense.
Structure of the present invention is simple, strong to the applicability of oil product, there will not be shutoff phenomenon.Cost is low, and a set of mechanism can realize the oiling of multiple lubricating point.When the signals collecting of metering mechanism is to master control system, during by PLC feedback signal, then increase video monitoring system, the intelligent menagement of lubrication system can be realized.As: volume read-out controls arbitrarily, and leak stopping is reported to the police, and volume read-out is added up.Arbitrary lubricating point breaks down, and other can work as usual.Owing to adopting the distributor mandrel rotated, have impurity strong adaptability, long service life, not easily blocking, pressure loss in piping is little.
Feature of the present invention: the 1. working principle of gear motor is used as oily flowmeter amount and clogging sensor.2. by oily fluidic distributor that stepper motor drives distributor mandrel 3 to combine with metering, judgment of clogging by above-mentioned two as oily fluidic distributor .3., can accurately control lubricant oil oil mass, the distributor mandrel that the present invention has, can connect different valve body oil outlets in different stable state positions; Quantitative lubricant oil is discharged.
In sum, the present invention is the multiple exit grease distributor that a kind of applicability on oil product is strong, measuring accuracy is not subject to the impact of the change of ambient temperature and system pressure.
